Details about the Samsung Galaxy S5 phone are starting to percolate. Bloomberg News reports that the S5 will have a 5.2-inch display screen that’s sharper than the screen on the current S4 model, and have an improved camera and better battery life. Other sites claim the new model will have a fingerprint sensor and a spiffy new physical design.

Just in time for Valentine’s Day last week, Facebook added more than 40 new gender terms for users to use with their profiles on the site, expanding from the binary male/female to include transgender, intersex and a whole lot more.

And finally, NASA says it’s solved the mystery of the jelly-shaped donut rock on Mars that seemed to suddenly appear in front of its Opportunity rover last month. The rock, as Mars-watchers know, looked like it showed up out of the blue in pictures the rover sent back to earth within the span of 12 Martian days. This set off all sorts of speculation about just how the rock got there, but NASA now says it was a broken-off piece of another rock that the rover ran over while it was exploring the area. Let’s hope Opportunity has its insurance card in the glove compartment in case the Martians file a claim.
